What was done
This narrative review synthesized the mechanistic basis and prospective therapeutic strategies for countering brain energy deficits in age-related neurodegenerative disorders, with a primary focus on Alzheimer disease. It examined physiological pathways of cerebral ATP generation (oxidative phosphorylation, glycolysis, ketone utilization, and exercise-derived lactate) and outlined interventions designed to restore or compensate for progressive glucose hypometabolism.
What was found
The abstract reports no quantitative empirical data or statistical results. It outlines potential therapeutic modalities including restoring oxidative phosphorylation and glycolysis, augmenting insulin sensitivity, correcting mitochondrial dysfunction, administering ketone-based interventions, delivering energy-modulating hormones, applying RNA therapeutics, and implementing multimodal lifestyle changes.
Why it matters
It frames cerebral energetic deterioration as a targetable driver of neurodegeneration that begins presymptomatically, highlighting metabolic rescue as an alternative or complementary therapeutic strategy to traditional disease-modifying targets.
Limits
The abstract provides no original experimental or clinical trial data, quantitative metrics, or systematic synthesis of treatment efficacy. Details regarding specific patient populations, clinical stages, and comparative treatment safety are absent.
